Can I stream to a Hard Drive

Hi,

Currently streaming Netflix (with proper subscription) to a Kodi Box on a little RK3229.

What would I need (and is it possible) to download my stream to a disk so I can view at will like on a PVR/DVR for the many times my (supposedly Fibre) Broadband is pants (thanks BT) ?

I’m looking at a Nvidia Shield Pro with .5TB Hard drive. Would that allow me to do above?

Thx,

Ouch!
